1. REAR VIEW MONITOR SYSTEM
1. REAR VIEW MONITOR SYSTEM
DRIVING PRECAUTIONS
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle with fixed
guide lines on the screen while backing
up, for example while parking.
INFORMATION
● The screen illustrations used in this text
are intended as examples, and may dif-
fer from the image that is actually dis-
played on the screen.
The rear view monitor system is a sup-
plemental device intended to assist the
driver when backing up. When backing
up, be sure to visually check all around
the vehicle both directly and using the
mirrors before proceeding. If you do
not, you may hit another vehicle, and
could possibly cause an accident.
Pay attention to the following precau-
tions when using the rear view monitor
system.
WA R N I N G
● Never depend on the rear view monitor
system entirely when backing up. The
image and the position of the guide lines
displayed on the screen may differ from
the actual state. 
Use caution, just as you would when
backing up any vehicle.
● Be sure to back up slowly, depressing
the brake pedal to control vehicle speed.
● The instructions given are only guide-
lines. When and how much to turn the
steering wheel will vary according to
traffic conditions, road surface condi-
tions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of
this before using the rear view monitor
system.
● When parking, be sure to check that the
parking space will accommodate your
vehicle before maneuvering into it.
● Do not use the rear view monitor system
in the following cases:
• On icy or slick road surfaces, or in
snow
• When using tire chains or emergency
tires
• When the tail gate is not closed com-
pletely
• On roads that are not flat or straight,
such as curves or slopes.
● In low temperatures, the screen may
darken or the image may become faint.
The image could distort when the vehi-
cle is moving, or you may become
unable to see the image on the screen.
Be sure to visually check all around the
vehicle both directly and using the mir-
rors before proceeding.
● If the tire sizes are changed, the position
of the fixed guide lines displayed on the
screen may change.
● The camera uses a special lens. The
distances between objects and pedestri-
ans that appear in the image displayed
on the screen will differ from the actual
distances.( P.143)

5. SETUP
■TIRE CHANGE CALIBRATION
1Select “Tire Change” .
The message appears and the quick dis -
tance calibration starts automatically.
The tire change calibration function will
be used when replacing the tires. This
function will adjust miscalculation
caused by the circumference differ-
ence between the old and new tires.
INFORMATION
● If this procedure is not performed when
the tires are replaced, the current posi-
tion mark may be incorrectly displayed.

6. TIPS FOR THE NAVIGATION SYSTEM
Accurate current position may not be
shown in the following cases:
• When driving on a small angled Y- sha ped

road.
• When driving on a winding road.
• When driving on a slippery road such as
i n

sand, gravel, snow, etc.
• When driving on a long straight road.
• When freeway and surface streets run in
pa ra

llel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during
hi gh

speed driving.
• When driving without setting the current
po sit

ion calibration correctly.
• After repeating a change of direction by
go ing

forward and backward, or turning
on a turntable in a parking lot.
• When leaving a covered parking lot or
pa rk

ing garage.
• When a roof carrier is installed.
• When driving with tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
• When using tires that are smaller or
l arger

than the factory specifications.
• When the tire pressure in any of the 4
t ir

es is not correct.
Inappropriate route guidance may occur in
the following cases:
• When turning at an intersection off the
d esi

gnated route guidance.
• If you set more than 1 destination but
sk ip

any of them, auto reroute will dis-
play a route returning to the destination
on

the previous route.
• When turning at an intersection for which
t here

is no route guidance.
• When passing through an intersection
f or

which there is no route guidance.
• During auto reroute, the route guidance
ma y

not be available for the next turn to
the right or left.
• During high speed driving, it may take a
l ong

time for auto reroute to operate. In
auto reroute, a detour route may be
shown.
• After auto reroute, the route may not be
ch ange

d.
• If an unnecessary U-turn is shown or
a nnou

nced.
• If a location has multiple names and the
sy ste

m announces 1 or more of them.
• When a route cannot be searched.
• If the route to your destination includes
g r

avel, unpaved roads or alleys, the
route guidance may not be shown.
• Your destination point might be shown
o n t

he opposite side of the street.
• When a portion of the route has regula-
tions prohibiting the entry of the vehicle
t hat

vary by time or season or other rea -
sons.
• The road and map data stored in the
n a

vigation system may not be complete
or may not be the latest version.
 If the vehicle cannot receive GPS sig-
nals, the current position can be
adjusted manually. For information on
setting the current position calibration:

 After replacing a tire: P. 2 4 4
INFORMATION
● This navigation system uses tire turning
data and is designed to work with fac-
tory-specified tires for the vehicle.
Installing tires that are larger or smaller
than the originally equipped diameter
may cause inaccurate display of the cur-
rent position. The tire pressure also
affects the diameter of the tires, so make
sure that the tire pressure of all 4 tires is
correct.
